FAQ
Q: Will my replaced data be sent to a server?
A: No. Everything runs locally in your browser. Your card data is never uploaded, archived, or cached — it is released as soon as you close the page.
Q: Does the search support regular expressions?
A: The search field is treated as a regular expression. Plain text works normally. If your input contains regex special characters and causes an error, the page will warn you — in that case please use a plain-text search instead.
Q: Is this tool free?
A: It is completely free, with no sign-up or login. Just open the page and start using it on your phone or computer.
